U-Coupon

U-Coupon is a discount balance measured in US dollars. You earn it from the people you are bonded to through the Kizuna Referral system, and it is spent automatically as a discount the next time you buy something on-chain. It is not a currency you can trade, gift, or withdraw — it exists to make your next purchase cheaper.

How You Earn It

U-Coupon flows between a Master and their Apprentices. Whenever one side completes an on-chain transaction — a Crystal pack from the Shop, or a paid Check-In tier — the other side is paid. Nothing is deducted from the buyer: the reward is added on top.

The Activity Rule

U-Coupon is only created for players who are currently playing. At the moment of a purchase, each receiver must have logged in within the last 48 hours; anyone who has not is simply skipped for that transaction. Nothing accumulates in the background and nothing is paid retroactively — so a Master who stops logging in stops earning, and starts again the moment they return.

How You Spend It

There is nothing to claim and no button to press. When you buy something on-chain, your U-Coupon is applied automatically:

50%

Maximum discount

is the most U-Coupon can take off a purchase. However large your balance, at least half of every price is always paid on-chain.

1

The game works out your discount: your whole U-Coupon balance, or the cap above — whichever is smaller.

2

You pay the reduced amount in the usual way. The discount is shown on the payment screen before you confirm, and again on the receipt afterwards.

3

The used amount is subtracted from your balance the moment the purchase is verified. If a payment never completes, nothing is spent.

Example

You hold $6.00 of U-Coupon and buy a $10 Crystal pack. The cap allows $5.00 (half of $10), so you pay $5.00 on-chain and $1.00 stays in your balance for next time. Each of your Apprentices then receives 1% of the $5.00 you actually paid.

Where to See It

Your balance and its whole history are visible in three places:

• Fortune — the U Coupon $ row shows your current balance.
• Referral (Social tab) — the same balance next to your Master and Apprentices.
• History — one line for every U-Coupon you receive (and from whom), and one for every discount you spend.

The Rules

Rule	Detail
Earned only from on-chain transactions	Crystal packs and paid Check-In tiers. Free rewards, Crystal spending and Trading Credit purchases never generate U-Coupon.
Calculated on what was actually paid	If a purchase was itself discounted with U-Coupon, the reward is based on the reduced amount.
Maximum 50% off	Applied automatically, never adjustable. A purchase can never be fully covered by U-Coupon.
Never expires	Your balance keeps until you spend it. There is no deadline and no decay.
Personal and non-transferable	U-Coupon cannot be traded, gifted, sold or converted into any other currency.
Receivers must be active	Logged in within 48 hours of the purchase, or that share is not created at all.

Getting Started

U-Coupon only flows where a referral bond exists. If you have not linked with anyone yet, or you want to invite friends and start earning from their purchases, read the Kizuna Referral page — it explains how Masters and Apprentices are formed, and why the very first login matters.
